Description
- Description: The CD28.2 monoclonal antibody reacts with the human CD28 molecule, a 44 kDa homodimer expressed by thymocytes, mature T cells and plasma cells
- CD28 is a ligand for CD80 (B7-1) and CD86 (B7-2) and is a potent co-stimulator of T cells
- Signaling through CD28 augments IL-2 and IL-2 receptor expression as well as cytotoxicity of CD3-activated T cells
- Applications Reported: This CD28.2 antibody has been reported for use in flow cytometric analysis
- Applications Tested: This CD28.2 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells
- This may be used at 5 μL (0.25 μg) per test
- A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
- Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
- Super Bright 436 can be excited with the violet laser line (405 nm) and emits at 436 nm
- We recommend using a 450/50 bandpass filter, or equivalent
- Please make sure that your instrument is capable of detecting this fluorochrome
- When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Staining Buffer (Product No
- SB-4400) to minimize any non-specific polymer interactions
- Please refer to the datasheet for Super Bright Staining Buffer for more information
- Excitation: 405 nm; Emission: 436 nm; Laser: Violet Laser CD28 antigen is a 44 kDa disulfide linked homodimeric T cell specific surface glycoprotein
- CD28 is a cell adhesion molecule of the immunoglobulin superfamily which is constitutively expressed on most peripheral blood T lymphocytes
- Moreover, CD28 is the critical T cell costimulatory receptor that provides the cell the important second activation signal by binding CD80 and CD86 which are expressed by antigen presenting cells
- In addition to its co-stimulation role, CD28 functions by preventing T cells from entering an anergic-hyporesponsive state or from undergoing premature apoptotic cell death
- In murine peripheral lymphoid organs and in the blood, all CD4+ and CD8+ T cells express CD28
- In the thymus, CD28 expression is highest on immature CD3-, CD8+ and CD4+8+ cells, and on CD4-8- cells that express alpha/beta and gamma/delta TCR
- The level of CD28 on mature CD4+ and CD8+ alpha/beta TCR+ thymocytes is two- to fourfold lower than on the immature cells
- Diseases associated with CD28 dysfunction include mycosis fungiodes and Sezary's Disease.
